Entanglement is a well-known resource in quantum information. In particular, it can be exploited for quantum key distribution (QKD). In this paper, we define a two-way QKD scheme employing GHZ-type states of three qubits obtaining an extension of the standard E91 protocol with a significant increase in the number of shared bits. Eavesdropping attacks can be detected measuring violation of the CHSH inequality and the secret key rate can be estimated in a device-independent scenario.
